Qtera Successfully Demonstrates First All-Optical Networking

                     Solution in Qwest 


             Communications' Next-Generation Network Field Trial

Trial Validates Technological Breakthrough Enabling Unprecedented Combination
                           Of Distance and Capacity


BOCA RATON, Fla., Nov. 23 /PRNewswire/ -- Qtera Corporation, a leading
developer of photonic networking solutions for the backbone of the Optical
Internet, successfully completed a field trial of its photonic networking
system with Qwest Communications International (Nasdaq: QWST). This trial is
part of Qwest's Next Generation All-Optical Network initiative, the first
completed on the industry's only commercial, all-optical test bed. Powered by
Qtera technology, purely photonic backbone networks will offer dramatically
reduced capital expenditures and operating costs, simplified network
architectures, rapid wavelength provisioning and much greater bandwidth
compared to today's optical networks. 
"We're extremely pleased to be partnering with an innovator and industry
leader like Qwest," stated Fahri Diner, Qtera's President and CEO. "The
flexibility and multiple fibers of Qwest's nationwide network make it an
excellent fit for our long-haul, purely photonic platform. This trial marks
the beginning of a new era in optical networking, one in which 'terabits over
megameters' is no longer a goal, but a reality." 
"We're looking to Qtera to be a key partner in our efforts to build an
all-optical, OC-192 IP backbone that will enable us to accommodate our
customers' ever-increasing bandwidth demands," said Vab Goel, Qwest's Vice
President of Emerging Technologies. 
Qtera and Qwest have collaborated on elements of the all-optical network
for more than a year. For the 30-day trial, Qtera installed a complete
photonic transport system, including Dense-Wavelength Division Multiplexed
(D-WDM) transmitters, receivers, optical amplifiers and optical add/drop
multiplexers in Qwest's all-optical test bed. Qtera's system carried 10 Gb/s
signals 2,400 km (or 1,440 miles) without any opto-electronic regeneration. 
"We are thrilled with the results of our first field test," said Bob Ade,
Qtera's Vice President of Product Development. "This represents the longest
unregenerated transmission at OC-192 over a service provider's existing fiber
plant." 
In addition to proving the maximum fiber throughput at the highest
capacity over the longest distance, Qtera also demonstrated its flexible
add/drop capabilities and its superior protection switching. With Qtera's
long-haul platform, carriers can add or drop any channel at any node. While
most systems provide only limited accessibility for wavelength manipulation,
Qtera offers 100% add/drop capability. Qtera's system also provides
unparalleled protection switching. During the Qwest trial, traffic signals
were restored within 10 milliseconds, faster than SONET's 50 millisecond
standard across far shorter distances. The simplicity of Qtera's network
architecture enables faster restoration schemes than traditional SONET rings,
regardless of the network size. 
"Carriers face an incredible and rapidly increasing demand for scalable
bandwidth and flexibility and they have to meet those needs while they drive
cost out of the network," said Chris Nicoll, Director of Infrastructure at
Current Analysis, Sterling, Virginia. "There is a new generation of optical
technology focused on photonics that is addressing the need for superscaling
optical bandwidth, without superscaling the cost. Aggressive startups like
Qtera are quickly bringing the new optical networking technology to market and
will force the incumbent vendors to take notice. It's hard to believe that, in
just 15 months, Qtera's solution has been built from scratch to the point
where it has completed successful field trials with Qwest." 
With the successful completion of its field trial, Qtera soon will be
conducting beta trials of its purely photonic networking platform with live
traffic.
